DEFINITION
3.1
Treatment
An
electro-mechanical
or
chemical
process
applied
to
one
or
both
sides
of
copper
foil
to
enhance
the
adhesion
of
the
foil
to
the
base
laminate.
3.2
Treatment
Transfer
Any
visible
bond
enhancement
that
has
transferred
from
the
surface
of
the
copper
foil
to
the
laminate
substrate.

Scope
This
test
method
establishes
a
procedure
for
determining
whether
the
adhesion
of
a
polymer
coating
to
an
inorganic
or
ceramic
substrate
is
above
an
adequate
level.
The
substrate
may
or
may
not
have
an
oxide
layer
on
the
sur¬
face.
The
test
can
be
inverted
and
used
for
determining
the
adhesion
of
a
metal
coating
to
a
polymer
film.

Pattern
Coating
The
coating
should
be
patterned
according
to
the
procedures
outlined
in
section

of
IPC-

The
pattern

one
for
the
initial
test
and
one
for
the
3

Test
5.3.1
Remove
two
complete
laps
of
tape
and
discard.
Remove
an
additional
length
at
a
steady
(not
jerked)
rate
and
cut
a
piece
approximately
75
mm
[3.0
in]
long.
5.3.2
Place
the
center
of
the
tape
over
one
of
the
grid
pat¬
terns
and
smooth
into
place
by
a
finger.
Rub
the
tape
firmly
with
the
eraser
on
the
end
of
the
pencil
to
ensure
good
con¬
tact
between
the
tape
and
the
film.
The
color
under
the
tape
is
a
good
indicator
of
contact
between
the
tape
and
the
film.
